GARBAGE-CREMATOR.

Application filed April 28, 1916.

To all whom it may concern: e

Be it known that we, CHARLES C. DE Larra and CHARLES H. SMITH, citizens of the United States, residing at- Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful 1mprovements in Garbage-Cremators, of which the following is a specication.

The object of the present invention is to provide an improved cremator suitable for domestic use'for cremating garbage.

One of the features of the invention is the construction whereby the lid may be effectually sealed, with the aid of water, to prevent the escape of gases from the device into the room where it is being used.

The cremator is adapted to be placed upon a household coal-burning range and is adapted to utilize the heat from the coal Vburning in such range, but it is nevertheburning range, the cremator being arranged in cooperative relation to such range. i

The same reference characters indicate the same parts wherever they occur.

The container for the garbage or other refuse is in the form of a cage and is indicated at 10. The term cage is used to imply that the container has openings for the escape of gases, regardless of whether such openings are perforations or the spaces between the wires of a fabricated container. ln the present instance the cage is made of sheet metal and has perforations 11 for the escape of the gases. The bottom 12 of the cage has a struck-up portion 13 adapted to expedite cremation and the escape of gases from the refuse.

The cage is adapted to set into an annular holder 14, and it has an external shoulder 15 adapted to rest upon an internal ledge 16 of the holder. The holder is adapted to rest upon the top 17 of a range, and it has a depending annular flange portion 18 Specification of Letters Patent.

adapted to set into one of the usual pot-holes in the top of the range, Fig. 2 showing the flange portion 18 in one of such potholes.

Three cooperative walls of the fire-pot are indicated at 19, 20 and 2l, and the coal o.

vrefuse and carry such moisture with it to the flue (not shown). lVhen substantially all the moisture hasbeen taken from the refuse in this way, the latter may be dumped upon the coal 22 and reduced t0 ashes.

The cremator is provided with a lid which comprises a depending annular flange portion 24 and a concave crown 25. This'lid coacts with the holder 14 to prevent the escape of gases from the cremator to the atmosphere, excepting the escape to the flue hereinbefore mentioned. The holder 14 is provided with an annular channel 26 adapted to receive the flange 24 and adapted to hold water 27 to provide a lute. The lid is provided with a handle 28, and the latter is fastened to the crown in the concavity of the latter by rivets 29. The concavity of the crown may be filled with water. This would .prevent extreme heating of the handle, and

would prevent the escape of gases through the rivet holes in case the latter were not completely closed by the rivets. The vapor from the garbage, on striking the watercooled lid, condenses and runs to the center before dropping. After the cremator has been installed and is ready to receive the water to seal the lid, such water may be poured into the concavity of the crown, and whatever water overfiows the rim of 'the crown will lodge in the channel 26.

lVe have provided the cremator with gasburning apparatus adapted to cause cremation without burning fuel in the fire-pot of the range. The holder 14, which is prefer` ably made of cast iron, is provided with a gas duct 30. This duct, in the present instance, is annular and is formed in the flange portion 18. A mixer for air and gas is inlijd dicated at 31 and is 'screwed into the side of the holder. A duct 32 forms communication between the mixer and the duet 30. The mixer is provided with a Coeli 33 to which a flexible gas tube may be attached. One or more gas burners 311 may be provided. le have shown three in the present instance. These burners are connected to the annular flange portion `1S and are in communication with the duct 30. rllhe openings for the emission of gas are indicated at 35. The burners are arranged in cooperative relation to lthe cage 10, the openings iaeing the cage so that the flames will impinge against the cage and apply the heat to the refuse in the most ellicient way. rl`lie burners project below lthe bottom ol the rage and have oli'set extremities 36 extending` toward a common center, said extremities having burner openings 35X arranged to direct the llames against the bottom ot the cage. These burners may be permanent parts ot' the cremator, and their presence would not interfere with the use oi the device in conjunction with coal or wood that might be burning in the lire-pot ol" the range.

The cage 10 ma)7 be lilted out of the holder 141 without removing the holdeil from the top of the range. lt may be observed 'that the bottoni 12 of the cage is eccentric with relation to the upper portion, holder, and pot-hole of the top 17. The purpose o1' such eccentricit-y is to enable the cremator to be turned to an angular position wherein the bulk of the refuse will be more nearly in the path traversed by the products of combustion from the ire-pot.

A detachable handle 'is indicated at 37. This handle has a lip 3S adapted to go into an inverted channel 39 formed in the holder 14. The handle has a portion 10 adapted to bear against a substantially upright surface of the holder 14, such as surface 41. When the handle 37 is used to lift the creinator the portion all is adapted to keep the cremator in an upright position while the weight of the. cremator is sustained by lip 38.

life claim:

1. A garbage cremator comprising; a cage, an annular holder therefor, and a lid haring a depression adapted to hold Water, and having a dependingI annular `flange encircling said depression, said holder having an annular channel adapted to receive said flange and adapted to catch Whatever Water orerilou's said depression.

2. A garbage eremator comprising` a cage, an annular holder therefor haring' a duct, said duct having an inlet ior combustible `gas, one or more gas burners arranged below and sustained by said holder in coperative relation to said cage, said burners being in communication with said duct, and a lid adapted to coact with said holder to inclose the upper part of said cage. o

In testimony whereof we have aliixed our signatures.
